Workingprinciple
Usually,theCNCcuttingsystemautomaticallyprocessestheprocessedpartsaccordingtothepre-programmedprocessingprogram(commonlyuseddrawingsoftwareAUTOCAD).Weputthepart'smachiningprocessroute,processparameters,toolmotiontrajectory,displacement,cuttingparameters(spindlerevolutions,feed,backtooling,etc.)andauxiliaryfunctions(toolchange,spindleforward,reverse,etc.)Cuttingfluidon,off,etc.),accordingtotheinstructioncodeandprogramformatspecifiedbytheCNCcuttingsystem,compileaprocessingprogramlist,andthenrecordthecontentoftheprogramlistonthecontrolmedium(suchaspunchedpapertape,magnetictape,disk,magneticbubble)Memory),andtheninputintothenumericalcontroldeviceofthenumericalcontrolmachinetool,soastodirectthemachinetooltoprocesstheparts.
Thewholeprocessfromtheanalysisofthepartdrawingtothepreparationofthecontrolmediumiscalledthecompilationofthenumericalcontrolprogram.ThedifferencebetweenCNCcuttingequipmentandordinarymanualandsemi-automaticcuttingequipmentwhenprocessingpartsisthattheCNCcuttingequipmentautomaticallyprocessesthepartsaccordingtotheprogram,whileordinarymanualandsemi-automaticcuttingequipmentneedstobeoperatedbyhumans.Weonlyneedtochangethecontrolofthemachinetool.Theprogramcanachievethepurposeofprocessingdifferentparts.Therefore,theCNCcuttingequipmentisespeciallysuitableforprocessingsmallbatchesofpartswithcomplexshapesandhighprecisionrequirements!
